Results regarding chemical control of Metcalfa pruinosa Say.

Abstract

Metcalfa pruinosa (Say 1830) known as citrus flatid plant-hopper, is native from eastern North America, an invasive species that extends its area from the south-eastern Canada to Florida (Mead, 2014), spreading later to other continents such as: Central America and Caribbean, South America, Asia and Europe (Strauss, 2010). We proposed to test the chemical efficacy of five insecticides (Calypso 480 SC 0,5%, Movento 100SC 0,2%, Nurelle D 50/500 EC 0,2%, Karate Zeon 0,5%, Mavrik 2F 0,5%), used against mobile forms (adults and larvae) of the species Metcalfa priunosa, the treatments being carried out on following plants: Inula sp., Salvia sp., Iris sp., Solidago canadensis, Helianthus tuberosus, Prunus cerasifera, Amorpha fruticosa, Yucca filamentosa from the "Al. Buia" Botanical Garden. Following the application of the treatments and the 2 weeks in which it was monitored their effect, the most effective product proved to be Nurelle D 50/500 EC with a 100% efficiency in the first 24 hours, followed by Karate Zeon and Mavrik 2F.
